If you are looking for dancing, loud music, and drunk people everywhere, Bar Smith is your answer. $10 cover for everyone (ladies and military, we are sadly not excluded from this) and you enter wonderland.
I love the upstairs bar, especially this time of year. It's a nice break from being hot and sweaty downstairs. It's usually EDM/house DJ's outside. Not as much dancing as downstairs, but you'll see the occasional raver going all out. Last time I was there, someone showed up in a bear costume! Downstairs is more hip music. It doesn't start to pick up until after midnight, aka after enough libations make the crowds go crazy. It's fun to go between upstairs and downstairs.
Carolina is a kickass bartender, she makes a mean whiskey ginger and has awesome green lipstick! Drinks weren't crazy outrageous expensive either. Bathroom line never seemed to last forever, although I don't think it's a classy enough joint to warrant an attendant. She was sweet though and gave me an extra piece of gum when I smartly opted out of a cigarette (yes, they have cigs for tips in the bathroom).
Overall, Bar Smith can be a fun time. Go into it expecting nothing, walk out drunk and sweaty.
